The optical and electrical characteristics of electrically-driven nanogap antennas are
extremely sensitive to the nanogap region where the fields are tightly confined and electrons …

Plasmonic nanocrystals in close-packed assemblies exhibit collective optical resonance and
strongly concentrated electric fields due to coupling. The spectral red-shift from the localized …

In the present work, silver nanoparticles (Ag 0) were synthesized under γ-irradiation from
silver nitrate (AgNO 3) precursor salt, at room temperature in aqeous medium without adding …

The crystallization of nanomaterials is a primary source of solid-state, photonic structures.
Thus, a detailed understanding of this process is of paramount importance for the successful …

In this work, we demonstrate the connectivity-dependent optical 'crack resistance'of a doped
epsilon-near-zero metamaterial (ENZ), which is distinct from conventional media. The optical …

Small size and narrow distribution are the key factors to improve performances of metal
nanocrystals due to nanosize effect. Here, a silver‐alkylamine complex–mediated single …

Nanocrystals with low size distribution are able to self-assemble into a 3D crystalline
structure called colloidal crystals or super/supracrystals. A rather large number of …

Metal nanocrystals (MNCs) have attracted large attentions due to their unique surface
plasmon resonance (SPR)[1–3] and excellent collective properties of their superlattices [4 …
